No reason, just wondering if you knew of them. I peruse their site occasionally to see if I'm missing out on something cool.

Centipede is running, needs its trackball rollers to be replaced and new balls would be nice. Monitor is functional, still dim, but after about 10 minutes it's warmed up enough that it's reasonably bright. Bright enough that I don't think I'll mess with it any further. it got a lot of use over the Christmas break. Unfortunately, the Tempest is acting up with a mathbox error, I just haven't gotten around to troubleshooting it yet.

OK, here it is: laser print on glossy inkjet paper, ironed onto single sided copper clad, dropped into hot water and toothbrushed until the paper fell off, then agitated around in a shallow pan of FeCl3 with a heat lamp shining on it. Total time, maybe two hours, and some of that time was finding all the necessary but scattered crappery.

Not perfect, but perfectly serviceable, I guess. A few places had somewhat skimpy traces, but I'll just beef them up with a little solder. I still have to drill it, but I can't find my tiny bits.

oooooo nice clean etch, Plinky! Congrats! Now, drilling: Carbide drill bits will last MUCH longer than HSS bits in that board material, but they're so much more fragile. Drill press is really a requirement. Fortunately, the carbide bits usually have big-ish shanks, makes chucking them easy.

Use a sacrificial backing board to drill through, too. You'll get MUCH cleaner holes.

Living in Pudstubble, of course I couldn't find any tiny bits locally. But you can find Dremel accessories, so I tried something new:

A #105 engraving bit. which worked fine. It's maybe a little slower than your standard twist bit, but it made nice clean holes with no blowouts. And I know that trick about using a backer board, but with this bit it wasn't necessary. I don't know how many holes will dull it, but this board has almost 250 holes & it didn't seem to be any slower towards the finish.
